Tyrepal replacement battery

[Gellyneck]

It's worth asking the question by email though to get a definitive answer. I've always found them really helpful TBH.

Think they have advised Shiffty, as in his previous, they don't sell the Solar Pro monitor separately unless I'm misreading it.

Just to revive this thread from a couple of years ago, the battery in our TyrePal Solar Colour Pro monitor recently died so I got in touch with TyrePal. This was their response:

"Unfortunately, we are not able to supply the internal battery for the monitor, due to strict import controls.................A new Solar Colour Pro monitor is available to purchase separately. The price is £55.00 including VAT and can be ordered by email. As a previous customer we can offer this to you for £44.00 each. Shipping is £9.55 per order. The original sensors will need registering to the new monitor."

A little online searching found a few batteries that are direct replacements for the TyrePal one so it begs the question, how come others can import them and TyrePal can't? Anyway, I ordered batteries on eBay and got two for little more than the price of one. Here's the link, but others are available. They took just over a week to arrive:

Pardon our interruption...

Here's the new battery (R) next to the old battery (L):

Replacement wasn't at all difficult (particularly compared to the Nextbase 522GW battery that I recently replaced). After removing four tiny screws from the base of the unit, the top lifts off easily to reveal this:

The battery is held down with some super-sticky black tape so needs carefully prising off with a wide-ish blade. It's best to first pull out its miniature plug from the circuit board. Some available batteries already have a miniature plug at the end of their wires but be aware that sometimes the polarity isn't correct (i.e. wires reversed). The batteries I bought had bare ended wires so I simply snipped the old battery's wires at about half way and soldered the new battery's wires to them, covering the connections with heat shrink, and matching the wire colours. A small piece of double-sided adhesive tape held the new battery in place and I also put some electricians tape across the upper face of it to insulate it from the exposed soldered connections on the underside of the solar panel (see photo). It was just a matter then of inserting the mini plug into its circuit board socket and switching the unit on briefly to check that the screen illuminated, which it did. Finally, replacing the top solar panel and fixing it with the four screws.

I then charged the unit through USB, which didn't take long to full charge. The TyrePal User Guide says that the original battery should last 60 hours between charges and it certainly seemed to last a very long time while used in our MH. It will be interesting to see whether the replacement battery has similar life. After several days it's still looking full.

Just as a point of interest, this is what TyrePal said when I asked why the battery would have failed:

"The Solar Colour Pro monitor is an electronic device with an internal lithium-ion battery, and we do advise that the device is not left under a hot windscreen unattended where it can be exposed to extreme heat. This will ultimately damage the internal battery and electronics. The solar PV panel is a ‘top-up’ charge, and the unit will charge in ambient daylight too."

But it's charged by solar it ain't going to work in a dark cupboard.

lol.

The solar PV panel is a ‘top-up’ charge gimmick, and the unit will charge in ambient daylight too shouldn't be exposed to sunlight."

Corrected

Mines been on the dash for five years battery still OK

offagen this is a really helpful post. I’ve just done the same and the unit powered back well. I put it on USB charge and it seems to have held.

Did you have to reprogram the sensors to the base unit after reinstalling? I’ve put it back into the van, but it hasn’t picked the wheel sensor readings back up yet. Is it a case of having to drive a bit to wake them up?

 

[Lenny HB]

Is it a case of having to drive a bit to wake them up?

Yes you do.

 

[Gellyneck]

Yes you do.

and, sometimes, a fair bit in our case!

If I've had them off for any reason, tapping them on the ground before refitting brings them to life.

 

[Gellyneck]

If I've had them off for any reason, tapping them on the ground before refitting brings them to life.

Even if I've not had ours off it can take 20+ miles before one of ours wakes up! It's one of the front ones closer to the monitor than the rears.

We've been having issues with sensors failing (2-3) over the last year or so and getting a wee bit peeved with the system. Might give a "non-Tyrepal" set-up a shot and see how they go.

Mine always wake up with a few rotations of the wheels..
I did have one a few years ago that had a completely flat battery and after replacing the battery it took ages to wake up but that's only happen once.
Mine are about 7/8 years old, when I put them on the new van I fitted new batteries they all worked straight away.

My neighbour across the road had loads of problems with his, I think there may have been a duff batch 7/8 years ago as a lot of problems reported around that time.

I just found this online. One way or another, I should be able to get them working again. The old battery was just as shrivelled as offagen’s but fitting the new one was fairly straightforward.

I’ll try giving the sensors a wiggle/tap with my finger first.

 

[Gellyneck]

I’ll try giving the sensors a wiggle/tap with my finger first.

I can even take a sensor off the valve sometimes and it doesn't trigger the monitor. Batteries all replaced a month or two back albeit no indication on the monitor that they were low.

Think Lenny HB could be right in that maybe out of a duff batch?

 

[Sheddy]

My old monochrome solar display has started displaying partial figures, and not retaining settings.
I had the same response from Tyrepal, sounds like battery failure but only option new display unit at £44 + shipping.
Now stripped down awaiting replacement battery.

Apologies for the delay in responding ManTheVan. I've been travelling all day.

I'm glad my earlier TyrePal post was of help. No, it wasn't necessary to reprogram the sensors. I did take the opportunity to change the sensors' batteries and seals. I find that if I switch on the TyrePal dashboard unit before starting the engine and pulling away the sensors usually spring into life within about 200-300 metres. However, if the dashboard unit is switched on after I've pulled away the sensors take much longer to register - maybe even a few miles. They won't register at all while stationary before driving.

Incidentally, in our case the TyrePal system is installed in our VW Up, which is used as our toad. It's so that we can monitor the toad's tyre pressures and temperatures while we are towing, with the dashboard display in the MoHo.
